I was wrong in the IP address that I test, but correct in the format and
the fact that it works.  You should be able to do PTR record checks by
formatting in this "in-addr.arpa" format.  An easy way to get this is from
the output of "dig -x" which shows the question section in the
"in-addr.arpa" format (and also in the answer section if it resolves).
